REQUIRES: can-execute

This tests that we abstract two peculiarities of unix in can_execute:
|
|
|
|
|
|
|
|
|
|
* Directories are executable, but we don't want to try to execute them.
|
|
|
|
|
* For shell scripts, we also need to be able to read them.
|
|
|
|
|
|
|
|
|
|
The PATH is constructed such that 'not' will first find a directory named
|
|
|
|
|
TestProg, then a file with executable bit but not readable and finally a
|
|
|
|
|
shell script which always returns false, which is what it actually tries to
|
|
|
|
|
execute.
|
|
|
|
|
|
|
|
|
|
If we want, it is probably OK to change the semantics of can_execute and this
|
|
|
|
|
test, but for now this test serves as a reminder to audit all the callers if
|
|
|
|
|
we do that.
